Abstract: An inputting method of computer and mobile telephone is disclosed. It is necessary for this method that there are 36 base codes and 5 single strokes. The base codes and the single strokes are configured on the 10 digits keys. It can input character without picking up it. The coding rule of all the words is same. It can directly input words with associative character for mobile telephone which has multiple selecting keys. The selecting keys are configured to multiple columns and multiple rows. When inputting English, it can input “space” automatically. For the high frequency word, it can display the word by only one key. That is to say a person can display text by pushing the selecting key only once. It can improve traditional inputting by associative character when a person uses computer.
